Recent forecasts for Helsinki on August 23, 2026, indicate persistent cloud cover, light rain or drizzle, and northwest winds of 6–8 m/s, which limit nocturnal radiative cooling and support overnight lows near 12–14°C. Official model guidance and station observations show daytime highs holding around 14–16°C under similar conditions, consistent with a cooler-than-average late-August pattern observed in recent days. These atmospheric factors—high humidity near 85–90% and minimal clear-sky cooling—position 14°C and 13°C as the leading market-implied outcomes at 54% and 30.5%, respectively, reflecting trader consensus on the narrow temperature range expected before any late-day clearing. Upcoming overnight measurements from local stations will refine resolution probabilities as the 24-hour period concludes.

This market will resolve based on the lowest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the lowest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 23 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the Helsinki Vantaa Airport Station, available here: https://www.wunderground.com/history/daily/fi/vantaa/EFHK.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
